Article Summary
- Dwarf Hairgrass (Eleocharis parvula) is a popular carpet plant for aquariums.
- It grows up to 4-6 inches in height and is suitable for foreground or midground placement.
- It creates a lush green carpet effect in aquariums when cared for properly.
Species Overview
Dwarf hairgrass, scientifically known as Eleocharis parvula, is a popular carpet species in the aquarium hobby. It belongs to the Cyperaceae family of plants and has variations within its species, including Eleocharis acicularis. Native to North America, Europe, and Asia, these aquatic plants can be found in various regions around the world.
This carpeting plant is considered a relatively fast-growing plant. It can reach a maximum size of around 4-6 inches in height, making it an ideal choice for foreground or midground placement in aquariums. However, it requires sufficient space to spread out its runners, so a minimum tank size of at least 10 gallons is recommended.
Maintaining suitable water parameters is crucial for the success of dwarf hair grass. It thrives best in slightly acidic to neutral pH levels (around 6.0-7.5) and prefers moderate lighting conditions. Providing adequate light intensity will promote healthy growth and prevent the plant from becoming sparse or leggy.
Propagation of the dwarf hair grass can be achieved through division or by planting individual runners into the substrate. This allows for easy expansion and filling out of larger areas within the aquarium.
One of the main uses of dwarf hairgrass is as a carpeting plant. Its dense growth habit creates a lush green carpet effect that enhances the visual appeal of any aquascape.
When properly cared for and given optimal conditions, this plant can transform an ordinary aquarium into a stunning underwater landscape.
Appearance

The carpeting dwarf hair grass is characterized by its fine, grass-like leaves that have a vibrant and bright green color. These leaves give the plant a fresh and lively appearance.
One notable feature of the dwarf hair grass is its ability to grow in dense clusters, which creates a lush carpet effect when planted on the substrate of an aquarium.
When fully grown, dwarf hairgrass can reach a height ranging from 2 to 4 inches. This makes it an excellent choice for foreground or midground planting, as it adds a visually appealing element to the aquarium.
One of the remarkable features of dwarf hairgrass is its enhancement under aquarium lights. When properly illuminated, this plant exhibits stunning colors that intensify the overall visual appeal of the tank.
Due to its dynamic growth pattern, dwarf hairgrass brings movement and energy to the aquarium. As it spreads and fills out over time, it creates an ever-changing landscape within the tank that captivates both fish and aquarists alike.
Dwarf Hairgrass Planting and Propagation
A larger tank provides more space for the dwarf hairgrass to spread and grow, allowing them to thrive. Plant dwarf hairgrass in a substrate that is rich in nutrients or sand. This will ensure healthy growth and provide the necessary nutrients for the plants to flourish.
Water Parameters
Dwarf hairgrass thrives in temperatures ranging from 68°F to 82°F (20°C to 28°C). It is crucial to maintain a stable temperature. Sudden fluctuations in temperature can stress the plant and hinder its growth.
This aquatic plant prefers slightly acidic to neutral pH levels, ideally between 6.0 and 7.5. A pH outside of the preferred range can affect the plant’s ability to absorb nutrients and may lead to stunted growth.
These aquatic plants can tolerate a wide range of water hardness, but it prefers moderately soft to moderately hard water. A range of 4 to 12 dKH (degrees of carbonate hardness) is suitable for this plant.
Very hard water hinder the absorption of nutrients, while very soft water lack essential minerals necessary for the plant’s growth.
Planting Preperations
Dwarf hairgrass thrives in a nutrient-rich substrate that provides good drainage. Opt for a substrate specifically designed for planted aquariums or one that is rich in nutrients like clay, peat, or specialized plant substrates.
Clean the substrate thoroughly before planting. Rinse it with water to remove any dust or debris. This will help create a clean environment for the roots to grow. Add a layer of nutrient-rich soil at the bottom of the aquarium to serve as a source of essential nutrients for the roots.
This carpeting plant grows best when there is a slight slope in the substrate. This helps to create a natural look and allows the hairgrass to spread and grow evenly. Gradually build up the substrate towards the back of the aquarium to create the desired slope. Avoid burying the entire plant, as this may cause it to rot.
Dwarf Hairgrass Propagation
Dwarf hairgrass naturally propagates through runners that spread horizontally. These runners produce new shoots which can be separated from the parent plant and replanted elsewhere in your tank.
Regularly trimming dwarf hair grass helps maintain its health by preventing overgrowth and ensuring even distribution throughout your aquarium.
To speed up propagation, optimize growth conditions such as lighting, nutrient levels, CO2 supplementation (if applicable), and regular maintenance routines. Providing sufficient lighting is crucial for photosynthesis. Ensure your tank receives enough light for optimal growth.
By following these guidelines, you can successfully plant and propagate dwarf hairgrass in your aquarium, creating a lush carpeting effect that enhances the beauty of your aquatic landscape.
Dwarf Hairgrass Tank Compatibility
Dwarf hairgrass is a versatile plant that can thrive in both freshwater and brackish water tanks. Its adaptability makes it an excellent choice for aquarists looking to add some greenery to their aquariums.
One of the advantages of this carpeting plant is its ability to coexist harmoniously with other small fish species like tetras or guppies. These tiny fish can swim among the grass blades, creating a natural and vibrant environment.
The dense growth of this carpet plant provides hiding spots for shy or smaller fish species, offering them a sense of security.
Exercise caution when considering tank mates for your dwarf hair grass. Large and boisterous fish may trample or uproot the delicate grass, causing damage to your plants.
Similarly, certain snail species like the pond snail (Lymnaeidae) and ramshorn snail (Planorbidae) may feed on the leaves of the hairgrass, impeding its growth.
Dwarf Hairgrass Care
Dwarf hairgrass is a popular choice for aquarium enthusiasts due to its vibrant green coloration and the lush carpet effect it creates in planted tanks. To ensure optimal growth and maintain its vibrant appearance, there are a few key factors to consider.
This carpeting plant thrives under moderate to high lighting conditions. Providing adequate light is crucial for photosynthesis, which fuels the plant’s growth. Make sure your aquarium setup includes suitable lighting that meets the needs of dwarf hair grass.
In addition to proper lighting, dense carpet hairgrass benefits from CO2 supplementation in planted tanks. Carbon dioxide helps enhance photosynthesis and promotes healthy growth.
Consider adding a CO2 system to provide the necessary carbon dioxide levels for your plants.
To maintain the lush green coloration of dwarf hairgrass, regular fertilization is essential. This ensures that the plant receives all the necessary nutrients it needs for robust growth.
Choose a fertilizer specifically formulated for aquatic plants and follow the recommended dosage instructions.
Dwarf Hairgrass Maintenance
To grow dwarf hairgrass, these plants require some maintenance to keep it looking its best. Here are a few tips:
- Regularly trim fast-growing blades to prevent them from overshadowing other plants or blocking light.
- Monitor growth rates and adjust lighting, fertilization, and CO2 supplementation accordingly.
- If hair algae appears in your tank, address it promptly by manually removing affected areas or using appropriate algae control methods.
By following these care guidelines, you can enjoy a thriving carpet of lush hairgrass in your aquarium while creating an aesthetically pleasing environment for your aquatic pets.
